But the 23-year-old Gossip Girl starlet isn’t the only one on the cover of next month’s issue, which lists the 50 most glam women of 2010. So is Avatar star Zoe Saldana (wearing Dsquared2) and Jennifer’s Body actress Amanda Seyfried (wearing Jasper Conran)!

“Most Stylish” Leighton on marriage: “If [marriage] was important to somebody I loved, maybe I’d think about it, but I don’t think that I’m the type. It’s not for me. I wouldn’t mind living together. [But] eventually I’ll have to get a separate house for my shoes!”

“Most Elegant” Zoe on her life: “I want to have more sex, travel more, drink more wine and love life… Don’t want to be any other woman but myself.”

“Most Down-to-Earth” Amanda on staying grounded: “There’s something empty about having your own VIP booth, and people staring at you, drinking and dancing—to get what?.. Maybe people [in Hollywood] wear really nice clothes, and they drive really nice cars—but that doesn’t make me comfortable. And if I’m not comfortable, it won’t be part of my life.”
